Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: Four parallel structures have been uncovered by trenching in the northern and eastern parts of this claim. These four sheared zones occur in intermediate tuff about 30 to 100 m south of large lenses of felsic volcanic rocks. The shears strike about N80 deg.W and dip steeply. The wallrocks have been altered to carbonate and chlorite and three of these sheared zones (#9,10,11,Bishop 1934) contain quartz ranging in width from 1 cm to 30 cm. The quartz is mineralized with pyrrhotite, pyrite, chalcopyrite, galena and sphalerite, plus gold; therefore these occurrences are quite similar in alteration and mineralogy to TD 13. The fourth prospect (#12) is a sheared and brecciated zone in the intermediate tuff that is well impregnated with pyrite but from which no gold was reported. DEPOSIT DESCRIPTION: Three parallel, silicified shear zones contain auriferous quartz up to 30 cm wide. Vein No. 10 was traced 100 m along its strike.
